There are some js conflicts on your site that prevent google search from working.
If you open your page with Google Chrome and press Ctrl+Shift+J you'll see the errors there.

Can you please try switching your theme to the twentytwelve theme?
If google search works there, then it's a conflict with your theme.
If google search doesn't work there, then it's a conflict with another plugin.
